This thesis introduces a new type of walking machine that appears promising due to its
relative simplicity and efficiency. After an introduction to a selection of previous walking
machines, the new machine’s history, ...

Energy absorption mechanisms have been investigated intensively for the past decades by
various authors and institutions, and numerous articles and other literature sources are available
in print, as well as on the ...

Globally, the art and the science of project management (PM) have contributed in no small measure to the advances in the delivery of Information Technology (IT) based solutions. In South Africa, it has been shown that IT ...

The global and competitive market environments have led to new challenges for both organizations and individuals in them. There has been a major change in the last twelve years since South Africa obtained independence in ...

Mozambique was a Portuguese province governed in terms of Portuguese legislation and principles. After the Mozambican independence in June 1975, and during the decade thereafter, all Portuguese legislation were re-evaluated ...

In the past two decades the refrigeration, air-conditioning and heat pump industries began the conversion from chlorofluorocarbon (CFC) refrigerants to hydrochlorofluorocarbons (HCFCs) and to natural refrigerants. This ...

When water vapour condenses at a sub-atmospheric pressure, the pressure drop may be a
significant fraction of the absolute pressure. Furthermore the pressure drop in a condenser
passage also reduces the absolute vapour ...

Currently, electrical resistance heaters are used to produce most of the hot water in South Africa. Increasing electricity tariffs make these devices very expensive. This study investigates the economic savings potential ...

Until very recently reactive maintenance was still used in the mining industry. Equipment failures occurred without warning and resulted in catastrophic breakdowns and large production losses and maintenance cost.
As ...

This project investigates the use of Self-Organizing Maps (SOM) for feature
recognition and analysis in 3D objects. Object data was generated to simulate
data obtained from 3D scanning and trained using SOM. The ...

This thesis presents the concept of remote (Internet) data acquisition and processing for control of EDM parameters. It incorporates aspects of data analysis while performing diagnosis of process behavior. A working ...

Stainless steel is considered to be the most appropriate material for the fabrication of plant and equipment in the food and beverage industry. The apparent ease by which the surface finish of the material can be kept ...

The relationship between the Mining House / Owner and Project House can be spectacularly successful for both partners (and has resulted in the emergence of a few successful new project houses and plant operation companies ...

An integrated project team strategy (IPTS) does not start with a detailed list of performance measures, but with the appropriate mindset of what is in the interest of the project. The purpose of IPTS is to unite the core ...

This thesis describes a real world application in the field of pattern recognition. License plate
recognition and face recognition algorithms are combined to implement automated access control
at the gates of RAU ...

This study describes a new class of mechanism to provide leg like motion, for use in a new type of walking machine, that is larger and simpler than electromechanical machines that are currently available. The mechanism is ...

Power electronics refers to electronic processing of electrical power. In this process the electrical
power is controlled by switching of power semiconductor devices as well as electromagnetically
stored in electrical ...
